Some Trichoptera, so-called net spinning caddis, eject the contents of their silkglands to build a nest for protecting themselves in a rapid stream. The adhesive protein formed by caddis worm Stenopsyche griseipennis McLachlan has been studied to obtain some basic knowledges such as the preparation of fibroin solution, the amino acid analysis, and the bonding strengths on test pieces. The protein was found to have the tensile strengths of the highest 14 kg/cm2 on iron and 7 kg/cm2 on pig bone, and the highest compressive shear strength 12kg/cm2 on iron.
A discuss ion is presented that includes results of the bonding strengths of Bombyx mori fibroin.
